  • Title: Bilateral internal auditory canal enlargement without acoustic nerve tumor in von Recklinghausen neurofibromatosis.
    Author: Kitamura K, Senba T, Komatsuzaki A.
    Journal: Neurofibromatosis; 1989; 2(1):47-52. PubMed ID: 2517023.
    Abstract:
    The common (and definitive) intracranial tumors in patients with one form of neurofibromatosis (NF), bilateral acoustic NF (NF-2), are bilateral acoustic neuromas. In this study, we present 2 cases with what appears to be another form of NF, namely, NF-1, who showed bilateral enlargement of the internal auditory canals. Bilateral caloric responses were remarkably impaired in both cases; a unilateral sensorineural hearing loss was observed in 1. No tumor was demonstrated in the enlarged internal auditory canals in either case. Although the pathophysiology remains uncertain, some patients with NF-1 show abnormal cochleovestibular function in association with bilateral internal auditory canal enlargement without an acoustic tumor.
